Millie Bobby Brown Unbuttons Her Shirt For Undies 'Couch Date'

Millie Bobby Brown is stunning in a new, Valentine's Day-inspired photo. The actress, 20, has been steadily promoting her Florence by Mills Fashion brand since its 2024 launch, and a new selfie this month is adding to the pile. Showing off a cute, skimpy look as she rocked plenty of red last week, Millie sizzled in teeny briefs and a shirt, going unbuttoned as she made her sexy look loungewear-inspired. Hinting at Valentine's Day, the British star opted for a "couch date" vibe, and fans seeing the Instagram repost went wild.

Scroll for the photo. Holding her phone in one hand, Millie highlighted her shapely legs in a just-about-visible pair of boy short undies in bright red.

Upping the romance vibes in a shirt with pops of red to match, the Stranger Things favorite modeled a button-down shirt in white, opting for floral prints as she kept her look girly. Rocking a few of her buttons undone, Millie upped the ante ever so slightly, completing her minimal outfit with a red pair of open-toe heels.

Throwing some '90s vibes into the mix thanks to her footwear and floral vibes, Millie stunned from a studio with a hanging rail of clothing behind her. Wearing her hair down and a little waved, the entrepreneur added ring jewelry and a French manicure, also sporting a light layer of flawless makeup as she channeled the matte trend. A caption read: "Millie for 'COUCH DATE' collection." Florence by Mills Fashion's Instagram, followed by over 197,000, has spent much of the past week ushering in its V-Day collection.

Millie made sure to alert her Instagram followers to her brand's offerings last summer, and this photo caught everyone's eye. Sizzling in the sun, the newly married star rocked a teeny bikini top and denim shorts from her brand, adding massive shades as her caption gave a nod to her "vacay in my flo denim." The "flo" was clearly a reference to Florence by Mills Fashion.

"I could follow trends, but Florence isn’t about following trends," Millie told Elle. "There’s a lot of that going on, especially on social media platforms, where you’re able to get this temporary satisfaction of everybody’s doing this, so we all have to do this. I don’t know if that’s the message that I want to put out there."

Also promoting the Valentine's Day collection was this look. Here, Millie Bobby Brown lounged around in cute striped PJs, posing with a heart-shaped pizza next to her. In May 2024, the actress made major headlines for secretly marrying husband Jake Bongiovi. The couple has since had an official, high-profile wedding ceremony.
